Parkinson's Clinical Trial Companion Accelerating Clinical Trials | Page 23

2014 MJFF webinar that focused on therapies with the potential to slow or stop Parkinson’s progression and highlighted the STEADY-PD III trial. A third peak took place in November 2015, after an October 2015 MJFF webinar and podcast on studies to slow or stop PD. A multitude of subject referral sources bolstered STEADY-PD III recruitment success (Figure 3, pg. 22). Referral sources were recorded at the time of screening and logged into case report forms. These data indicate the top four referral sources were: site personnel (53.8 percent); neurologists (24 percent); Fox Trial Finder (10.2 percent); and MJFF communications (3.9 percent). Discussion By having a comprehensive recruitment plan and involving key stakeholders early in the planning phase of the clinical trial, STEADY-PD III was able to successfully recruit its full target population six months ahead of schedule. They identified study and site level barriers that had the potential to negatively impact recruitment, and were able to develop a strategy to mitigate them. One important component of that strategy was implementation of a comprehensive outreach and awareness campaign. Stakeholders such as PDF maximized peer-to-peer engagement via the PAIR program and local events including the Brain and Health Fair and the Unity Walk; NPF harnessed the power of social media through webinars and press releases; MJFF leveraged technology such as Fox Trial Finder to connect volunteers to trial teams; and The Muhammad Ali Foundation increased participation of historically underrepresented minority populations with community engagement, translation of materials and outreach through the “Southwestern Parkinson’s Newsletter.” The use of local grassroots events and social media activities, combined with a proactive approach to recruitment, helped to engage and make aware a broader population than would have been possible for clinical trial sites alone. This approach also enabled study teams to connect with a more diverse population of patients who obtain their information from a variety of media and news sources. While the impact of these efforts is somewhat challenged by self- reported referral source data (Figure 3, pg.22), we posit that this is less about the efficacy of these efforts and more about challenges stemming from memory recall bias in referral source attribution. Greater efforts such as interviewer training, better referral source definition and alternative means of data collection should be considered for future recruitment campaigns to improve the accuracy of attribution. 10 Continued on page 22 Figure 1.
